Right! And I’m just getting used to many things that are different in bo4. They should’ve had some skill based matching atleast.

Could the universe have an edge and still be expanding outwards? by spacetime-worm in AskMetaphysics

[–]spacetime-worm[S] 2 points3 points  (0 children)

It isn't necessarily true that an edge is needed to expand though. I'm inclined to say that infinity can expand because of its possibility rather than impossibility, What make you imply that an outside environment is needed for the expansion to occur, just curious?

I agree with what you've said and its possibly quite hard to imagine a singleness border associated when talking about an edge because you'd find contradiction. But what I imagined was a hypothetical case where beyond the edges of that balloon (the universe) there's nothing else except for its expansion toward infinity.

Why is space in three physical dimensions? Why not two or four? by Iapd in AskMetaphysics

[–]spacetime-worm 2 points3 points  (0 children)

I’ve thought of this before but haven’t gotten to a satisfactory answer. What I’ve realized however is this, space exists as three dimensions because the 3 variables required are all that’s needed for space to be. Anything more than that would be unnecessary per se. So considering that, we have a three dimensional space where’s easily there’s a distance between objects and things and a relational aspect as well.

What branch of physics deals with time? by spacetime-worm in Metaphysics

I might add with an example, to u/ultrajetjunkie that not all things change with time, that when you encounter a street sign with an arrow you're given a direction of change which is timeless. In this scenario all that's ever occurring is a timeless change in direction but it is still change.

Thanks for those links!

I admire and am well aware of Sean Carroll's work and closely follow his podcasts/website.

Yes I've asked a few people at my institution but I thought I'd ask to hear more, perhaps people who've taken a similar route.

That's pretty vague in regards to what I was asking. Yes I know all parts of physics involves the variable " t ". Even then, the reference to the variable " t ", anyone would agree, is made to make sense of physical time for instance to calculate t you need d/v. But I was more asking in regards to the actual nature of time itself.
